JULIUS KUI-INERT, 0F BRESLAU, GERMANY;

DRILLSHARE.

To all 'whom' t may concern.'

Be it known that I, JULIUs KUHNERT, a subject of the German Emperor, and resident of Breslau, Germany, have invented certain new and useful Improvements in Drill-Shares, of'which the following is a specification.

This invention relates to improvements in drill shares, and more particularly to a device for an easily disengageable attachment of the pressure rollers to drill sha-res, which can easily be applied to already used, old machines without necessitating an essential alteration of the same.

The device consists of a stay, which closes the front end of the roller supporting strap and which is provided with grooves for engagement with the diverging draw-bars of the drill share and with a rearwardly directed wedge engaging the angle formed by the bars, the latter being thus adapted to be removably secured to the stay by means of an ordinary screw-joint.

The accompanying drawing shows the iniproved arrangement.

Figure 1 is a longitudinal section through the device on the line A-A of Fig. 2 which is a plan view ofthe same, Fig. 3 is a plan view of the connection-stay on a larger scale, and Fig. l a cross section through the attachment, on the line B-B of Fig. 2, also on a larger scale.

porting strap b is at the front closed by a stay c.

Z is the drill share with its dive-rging draw-bars e. For connecting the strap with the draw-bars, the stay c is provided at one end with grooves c1 for engagement with the bars, and at the other end with a rearwardly directed wedge c2 which engages the angle formed by the bars, so that the parts, which are thus already firmly connected, can be secured to each other' by a screw-joint f of ordinary type.

What I claim is:

A device for a disengageable attachment,
